Those of you with rooted first generation Fire TVs can now update to the latest 184.108.40.206 software version because rbox has released a pre-rooted ROM version. You can download the ROM at the usual place and install it using TWRP. I had a bit of a hiccup with my update capturing setup, which is why a ROM for the Fire TV 2 is not available yet. I was able to finally capture the Fire TV 2 update this morning and have passed that on to rbox, so hopefully he’ll find time to release a pre-rooted ROM for the Fire TV 2 soon.
If you have the means, be sure to show your support by donating to rbox. Rbox has made some progress on TWRP and ROMs for the Fire TV Stick during the last couple weeks, but there’s still no word on when those will be released. As always, these pre-rooted ROMs are released so that those with rooted devices can update to the latest software version without losing root. Your device must already be rooted to install these ROMs, so therefore, they will not help you root an unrooted device. To see if your Fire TV 1, Fire TV 2, or Fire TV Stick can be rooted, see my rooting starters guide.
